Senior appointments to the state's corruption watchdog will no longer require bipartisan support.

Mr Wellington, the independent Member for Nicklin, is on the Parliamentary Crime and Misconduct Committee (PCMC).

He says a promise by the Government to consult over appointments means nothing.

"Those people need to feel confident the person or organisation they are making that complaint to is totally independent of the Government," he said.

"The appointment of these people to the leadership positions required the support from the Opposition.

"That is no longer going to happen under the Government's proposal and it just shows to me an arrogant style of government."

Mr Wellington says previous governments tried to ensure the independence of the CMC.

"The perception in the community that at all times the CMC will investigate complaints as best they can is you remove the perception of bias," he said.

"The way you remove that perception of bias is to ensure that the people in these leadership positions are appointed with the support of the Opposition."

Attorney-General Jarrod Bleijie has defended the planned changes.

Mr Bleijie says there will still be consultation and other important positions like judges do not require endorsement from the Opposition.

"There's other positions in Queensland which are independent statutory officers that you consult with the relevant parliamentary committees but not necessarily getting bipartisan support," he said.

"The reason is we're trying to de-politicise the CMC."

However, Opposition Leader Annastacia Palaszczuk says it will not support legislation to overhaul the CMC.

Ms Palaszczuk says the Government should not be able to appoint whoever it likes.

"If there is no bipartisan support for the new chair of the CMC and the new CEO, we will oppose this bill in its entirety," she said.

"Bipartisan support is fundamental so the public will have confidence in the operations of the CMC."

The laws also include a special provision to extend the appointment of acting CMC chairman Ken Levy until October.

Dr Levy is being investigated by a select ethics committee over claims he misled a parliamentary hearing.

Queensland Council for Civil Liberties spokesman Terry O'Gorman says the state's corruption watchdog is set to be politicised.

Mr O'Gorman says it will result in political appointments under the direct control of the Government.

"It will neuter and greatly change the way the Crime Corruption Commission operates and the respect with which it is held in the community," he said.

"As soon as it is seen that appointments are done only by the Government, without any consultation with the Opposition, then the standing of the Crime Corruption Commission will drop significantly in the public's mind."
